HaxeFlixel
An open-source 2D framework on Haxe and OpenFL with sprites, input, cameras, collision, and common game structures.
Why use it
One codebase targets multiple platforms and works well for pixel games, jams, and code-led 2D production.
Where it fits
Find engines, frameworks, code libraries, version control, and production automation.
What to check
The Haxe ecosystem is comparatively niche, so plugins and platform-specific experience can be harder to find.
